BD5236FVE-TR

Overview

The BD5236FVE-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features an adjustable delay timer and operates within a reset active voltage range of 0.95 to 10 V. The typical under-voltage detection voltage is 3.6 V with a precision of ±1%. The device utilizes an open-drain output type and maintains a low reset active state. Circuit current consumption is specified at 0.85 μA when the detection voltage is 4.8 V. It is housed in a VSOF5 package and supports RoHS compliance.

Feature Summary

• Incorporates an adjustable delay timer function for customized reset timing control.
• Features an open-drain output configuration suitable for various logic interfaces.
• Provides precise under-voltage detection with a typical threshold of 3.6 V.

Applications

• Monitoring power supply voltages in electronic circuits
• Providing reset signals for microcontrollers and digital systems
• Ensuring system stability during power-up and power-down sequences

Procurement Notes

Verify the obsolete status and last-time-buy designation before procurement planning. Confirm that the VSOF5 package matches the target PCB footprint. Ensure the open-drain output polarity aligns with the receiving circuit's input requirements. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when an adjustable delay timer is required alongside standard voltage monitoring. The wide reset active voltage range accommodates various supply levels. Consider the low circuit current for battery-powered or energy-efficient applications. Verify that the open-drain output capability meets the interface needs of the downstream components.

Part Context

This part belongs to the BD5236 series of voltage detectors from ROHM Semiconductor. It shares similar specifications with the BD5236G variant but differs in package type, utilizing VSOF5 instead of SSOP5. The series is designed for general-purpose voltage supervision in consumer and industrial electronics.

Replacement Considerations

The BD5236G-1 is listed as a recommended replacement with the same pinout. Verify package compatibility between VSOF5 and SSOP5. Confirm that the slightly different precision and current consumption values meet the design requirements.
